The Manhattan Institute's Jim Manzi has written a great column lucidly explaining why the economic policies of the Democrats under Obama threaten entrepreneurship, the ultimate source of innovation, productivity enhancement, and economic growth. Here's his conclusion:
Like the college students who stayed up late to hear Obama’s campaign speeches only to find his first significant action to be a stimulus program that will transfer about $1 trillion from them to the Baby Boomers, Silicon Valley Obama supporters may find themselves in an uncomfortable environment. A government-dominated economic era may not be an auspicious one in which to start companies that threaten big, incumbent corporations with lots of political clout.
The concept of “animal spirits” recognizes that not all economic decisions are made entirely with spreadsheets. Some people start companies because they’re driven by a dream that transcends rational economic calculation. But most successful entrepreneurs are pretty serious about comparing risks with opportunities. Higher tax burdens raise the price of entrepreneurship. When you raise the price of something, then, all else held equal, you usually get less of it. Given that something like 7 million people in the U.S. work in companies that are or were venture-backed, including a majority of the employees in high-growth sectors of the economy like computers and software, this is likely to matter a lot in the long run.
